'l The-1mouriting3that 5I have Iprovids-:fd involves,

generally a frame A applicable to the wall to be fixed therein, a closure B for the `frame involving relatively movable sections and operating means C for the closure.

The frame A that I provide may vary widely in form, shape, proportioning and construction. In the case illustrated I show a preferred form of frame in which case the frame is a simple, rectangular box-like structure involving, generally, a top wall 20, a bottom wall 2|, side walls 22 and a back 23. The several elements or parts of the frame may be integrally or otherwise joined so that the frame forms a permanent or xed structure in the nature of a box open at the front. In the preferred form of the invention I form the frame of sheet metal although it will be apparent that any other suitable material or combination of material may be employed as circumstances require.

I provide mounting means for the frame A whereby the frame is applied or xed to a Wall or the like. In t'he case illustrated the facing of the wall is provided with an opening 24 which receives the frame with suitable clearance allowing the frame to project into the wall to a point where the back 23 is in the vicinity of the xed elements |2 of the wall. The mounting means illustrated in the drawings involves a iiange 25 at the outer edge -or edge portion of the frame and one or more fasteners 26 securing the frame to the wall members l2. As shown in the drawings the fasteners 26 may be simple screws engaged through the back 23 of the frame to enter the wall members I2 as clearly illustrated in Fig. 2 of the drawings.

The mounting flange 25 is a marginal flange provided at the front or outer end of the frame and it may be a continuous flange extending entirely around the frame to project therefrom in a manner to overlie the face l5 of the wall entirely around the opening 2li to receive the frame. The various parts of the Iiange project from the outer edge portions of the top, bottom and side walls of the frame. The flange may be an integral extension or continuation of the frame parts or it may be formed separately from the other elements of the frame and attached thereto through parts 28 secured to the walls of the frame, as illustrated in Fig. 3 of the drawings. In practice it is ordinarily desirable to make the flange 25 substantially uniform in size Iand shape as it extends around the frame and in the particular design illustrated it is rounded at the corners.

The closure B that I provide is a sectional element preferably in the form of a simple, at, or substantially flat, panel shaped and proportioned to form a cover or closure overlying the frame parts including the mounting flange when it is in the closed position as shown in Figs. l and 2 of the drawings. The closure preferably involves two simple shiftable or relatively movable sections, an inner or lower section 30 and an outer or upper section 3|.

The inner section 35 of the closure serves to cover or close the lower portion of the frame while the upper section overlaps the lower section and serves to cover the upper portion of the frame. The inner portion is pivotally connected to the frame and in the preferred form of the invention a simple hinge 32 pivotally connects the lower edge portion of closure section 30 with the lower edge portion of the flange, preferably the outer edge of the iiange 25 projecting from the bottom wall 2|. The inner section 30 may be substantially rectangular in form, in which case it has parallel side edges 35, a bottom edge 36 and a top edge 31. The section 30 is preferably made sufciently wide to cover or substantially cover the frame A at the lower end portion thereof. In the drawings I have shown the section 30 wide enough to completely overlie al1 portions of the frame at the lower part thereof including the flange parts 25.

The inner section 39 of the closure forms the mounting or carrier for the implement handled by the structure. In the case illustrated a can opener D is mounted on or applied to the closure section 30. The particular can opener shown ing the drawings involves a mounting bracket 4G secured to the inner side of closure section 35 and having a projecting outer end portion el projecting a substantial distance beyond the top or outer edge 31 of section 30. The opener includes a suitable can opening mechanism 42 carried by the projecting portion 4| of the bracket All and an operating handle 43 is provided to operate the mechanism 42. The handle illustrated is rotatably supported by the portion 4| of the bracket and is operable to what may be termed a folded position where it overlies the portion of the bracket 40 secured to the section 30.

The outer section 3| of the closure is mounted on or carried by the inner section 35 and is shiftable relative thereto between a retracted position such as is shown in Fig. 3, and an extended position such as is shown in Fig. 2. When the outer section 3| is in the retracted position, as shown in Fig. 3, it is practically conined to the inner section 3@ so that little or no portion of it projects beyond the section 3|) whereas when it is in the extended position there is only a limited portion of it overlying the section 30 while the major portion of it projects from section 30 and the projecting portion covers or overlies the upper portion of the frame in the manner that the section 3U covers or overlies the lower portion of the frame, to the end that the sections 3B and 3| combined completely overlie or cover the frame including flange 25. It is to be understood, however, that it is not necessary for the closure to completely overlie all parts of the frame in that an effective design may be provided wherein the flange is visible beyond the edges of the closure, although I prefer to cover the ange as I have shown in the drawings.

The outer section 3| of the closure, like the inner section, may be a simple at plate and in the design illustrated it is substantially rectangular in form having a lower or inner edge 5E, an outer or upper edge 5| and parallel side edges 52. The upper corners of plate section 3| are rounded as are the lower corners of plate section 3|?.

In accordance with my construction I provide guide means slidably connecting the closure sections and 3| and although I may employ various structures to effect the desired sliding connection between the sections I prefer to establish this connection by providing simple guide ilanges 55. The guide flanges 55 are provided at the side edges of one of the closure sections, preferably the outer closure section 3|, and they are formed to turn in so they engage over the side edges of section 30 to overlie the back or inner face 56 of section 38 which is the section to which the bracket is secured. In the particular case illustrated one continuous guide flange is provided at each edge 52 of section 3| and the guide flanges are co-extensive fwith theise'ction': 3 litcprovideeainplebearingzengagementpwith theasection'i.
